I also feel the need to comment that, while there are GLOs at all-or-mostly engineering schools, I would think that the GLO would cater to that lifestyle. I can't imagine how different my sorority would be if my entire chapter were engineering majors!! There would be a LOT more studying and a lot LESS late night activities

And to be completely honest, I just think there would be less activities in general.
At my school, there is ALWAYS something going on (panhellenic meetings, philanthropy event, intramural game) but I think at a school where nearly everyone is an engineering major-- the entire Greek system would conform to their needs and capabilities as students. My chapter would definitely be left in the mud if we had all of our current activities and 140 engineering majors- my 'would-be sisters' would have such a hard time planning, participating, and keeping track of things..
